What is the minimum clearance required on the control side of a floor furnace?

The minimum clearance required on the control side of a floor furnace is 18 inches. This distance is crucial for ensuring safe operation and maintenance access to the furnace control mechanisms. Maintaining this clearance helps to prevent any potential hazards such as obstruction of airflow or interference with the control operations of the furnace, which could lead to malfunction or unsafe conditions. Adhering to this regulation is essential for compliance with safety standards and for promoting efficient heating performance within the heating system. This requirement also allows for sufficient space for servicing or troubleshooting the furnace, which is vital for ensuring safe and reliable heating in any given space.
